This lesson using bamboo steamer mats gives 2 creative ideas using kitchen equipment. The list of materials required is comprehensive, yet it is easy to see where individuals can use substitutes according to their geographical area.
Instructions throughout are clear, detailed, but at the same time concise, making them easy to follow. The photography showing placements were excellent, although I would have liked one showing more of the original drilling for the first design. The photo for the second design was more helpful to me.
In the notes to the first design, Mark says "the greater the number of binds, the greater the structural integrity of the foundation" is worth highlighting. Not having enough binds is a fault many beginners would have.
The notes for the second design give excellent information on binding the top dowels into some triangles and reasons why this is done, especially the highlighted photo of the main structural triangle.
This ebook lesson is well worth having.

In both designs, the photos of side angles are very helpful
